When you or someone else says, babies cant walk, you will find yourself only able to crawl and too weak to stand. After you hear babies cant walk, you can also be triggered to have only certain baby like behaviors by saying or hearing for example, babies suck their thumb, babies cant use the potty, etc. But if someone says, stop pretending to be an adult, you will regress to a complete baby until the person who triggered you says, time to play adult.
